Same PDF with changed function

Digging a little bit deeper into it I encountered that it is the exponential
function of the separation colorspace:

24 0 obj <</C0 [1.0 ] /C1 [1.0 ] /Domain [0 1 ] /FunctionType 2 /N 1 /Range [0
1 ] >> endobj

If I change it to

24 0 obj <</C0 [1.0 ] /C1 [0.0 ] /Domain [0 1 ] /FunctionType 2 /N 1 /Range [0
1 ] >> endobj

it works well also with poppler. But acrobat always shows the text in any
combination of C0/C1 with values 0.0 and 1.0!!!
